	Builds a list of objects with all child objects (`obj.OutList`)

	This function is mostly useful for Arch Workbench objects.

	Parameters
	----------
	objectslist: list of App::DocumentObject
	A single scripted object or list of objects.

	recursive: bool, optional
	It defaults to `True`, in which case the function
	is called recursively to also extract the children of children
	objects.
	Otherwise, only direct children of the input objects
	are added to the output list.

	_donelist: list
	List of object names. Used internally to prevent an endless loop.

	Returns
	-------
	list
	List of children objects that have their `MoveWithHost` attribute
	set to `True`.
